Is it possible to create an application with vb.net to track a users usage of Excel, Word and another application called lets say - Userapp.exe
At work we have been asked to create a diary of our days work and since most of my work is in excel, word and a custom application I have built, I was wondering if it was possible to track the usage of these programs store the data in a datatable and then save it to a access db.
Usage of the program would mean the time that the file is open on the screen, that way the time a program is open but minimised in the taskbar would not be counted.
The data table would have these headings -
1. Program (i.e excel, word etc.)
2. Name of File used
3. Time used in program
I'm trying to creat a program that tracks the sales of five products all with different monetary values. I'm trying to display the total number of each product sold, a combined total of products sold, and the total sales value. So far I'm only outputing the value of one of each product, I think there is a problem with the loop somehow. [code]

I made this thread a discussion thread instead of a question thread because I would like hear opinions on how I should do this best. Right now, what I am wanting to do is done with macros inside of microsoft excel spreadsheet and I think a program that is easier to control and perform updates and that did the same thing might be simpler for the end-user and for me. The Excel sheet works fine for right now but editing the macros when a change needs to be made is a pain.
I would like to have a VB program where a user will scan in a serial number and a tester number and then that information will be stored in a sheet, like excel or pdf or something, and then when that sheet reaches the limit of parts that should be on a certain sheet, save the sheet to a specific folder and then print the sheet out.
I will do a step by step breakdown to make it a little more clear what I am trying to do.
Step 1: User determines what kind of part is being scanned (Type 1, Type 2, Type 3, Type 4)
Step 2: User scans the barcode on the part. That data is entered into a sheet as well as the date and time when the part was scanned.Step 3: User then scans a barcode telling the program what station the part come from (Station 1, Station 2, Station 3, Station 4). Then the sheet is saved and waits on another part to be scanned, going back to Step 2.
Step 4: When the sheet meets the maximum allowed parts per sheet, determined by what part is being scanned, the sheet is saved into a folder and the prints itself out.I'm not necessarily looking for code for this idea but more of a 'Well, I would do it like this.." type thing.
I have a tracking device CT-04 car tracker that i am trying to integrate with my vb.net desktop application. I have the protocol from the manufacturer (redview) that contains the commands to send to the tracker unit and from tracker to the server. My application is in vb.net .
I wanted to know how i can send the commands from my vb application i.e can i still use vb.net to send these commands to the tracker through gprs?
what do i require in terms of hardware and software from my side in order to send these commands through gprs (not SMS ) to the tracker unit and to receive data from the unit.
I'm using VB 2010 Express with a local Access DB. On the form I have a DataSet, a TableAdapter, a BindingSource that points to the DataSet (and the DataMember is the same table as the TableAdapter), a BindingNavigator that points to the BindingSource and finally a DataGridView that points to the BindingSource also.
I have added a Save button to the BindingNavigator. I want to enable / disable the Save button depending on whether there are changes in the data to send back to the Access DB. I think this is the code, but I am not sure if I'm really doing what I think I am (i.e. I am concerned I will assume something turns out to be wrong) or if there are better ways.
I am also uncertain what event to use to respond to. I have guessed at CellLeave, but I could be wrong and there might be much better choices. Finally I've been told that it's different if it's a DataTable, but I do not know enough to determine when something is a DataTable?
Private Sub CompClass_DataGridView_CellLeave(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles CompClass_DataGridView.CellEnter Me.BindingNavigatorSaveItem.Enabled = Me.Component_MI_DataSet.HasChanges End Sub
I have two Buttons, button A and button B. After 100 clicks on button A a pictures is displayed and after 10 clicks on button B another picture is displayed. I wanna have two different timers as to timing each response (button a or button B respectively) without these two timers to be timing both these responses. I try to do this for over one month!
I am making a webcam capture program in vb.net to scan qr codes. I found some examples that show tracking a certain color, but that wont work because the qr codes have different colors. some are red, blue, purple, black, and green. I am using the touchless sdk to capture the video. How would I go about tracking the person's hand holding a 1"x1" cube? I am trying to reduce the "background noise" that the scanner has to try to read through.
I am creating a program to manage seats in an auditorium. The person who will be using this program will need to be able to use the program to print tickets, mark seats as broken, or clear a seat.My thoughts have been of using checkboxes and saving the stuff in the My.Settings. There has to be an alternative to putting 450 checkboxes in, Labeling them, naming them, and so on and so forth. I started putting them in the program seen below:And then I remember of course, I need it to be able to do multiple days. So suddenly things get really hard.
I would like to use C# for an application I'm building, but the application makes heavy use of automation (i.e. Excel, Word).
Is it feasible to use C# for such an application? It used to be a nightmare to use C type languages for things like parameter lists with null arguments etc..?
I have created a bunch of user settings using my.settings.*** and only save these upon form_closing for the time being.I wanted to save the settings every 30 or so seconds, so I created a timer with 30 second tick intervals. Inside the tick event of that timer I included the code that I had in the form_closing event.While it works to save the settings, it also 'freezes' or 'skips' the main program for about a second or 2 while it's saving. The code to save settings includes looping through at least 2 arrays and adding them to the settings specialcollection object one item at a time.Is there a better way to accomplish this, without 'locking' up the main form for a second or so? Is it feasible to loop through all the settings in a different thread (can you access settings cross-thread)?
I have a small-scale WPF application using VB.net as the code behind and I want to add certain features, but i'm concerned about performance.
1) My app interacts with a third party database to display "realtime" data to the user. My proposed method is to create a background worker to query a database every 30 seconds and display the data. I query about 2,000 records all long integer type, store them in a dataset, and then use LINQ to create subsets of observable collections which the WPF controls are bound to.
Is this too intensive? how much memory am i using for 2,000 records of long int? Is the background worker querying every 30 seconds too taxing? will it crash eventually? Will it interfere with the users other daily work (excel, email, etc)?
2) If an application is constantly reading/writing from text files can that somehow be a detriment to the user if they are doing day to day work? I want the app to read/write text files, but I don't want it to somehow interfere with something else the person is doing since this app will be more of a "run in the background check it when I need to" app.
3) Is there a way to quantify how taxing a certain block of code, variable storage, or data storage will be to the end user? What is acceptable?
4) I have several list(of t) that I use as "global" lists where I can hit them from any window in my application to display data. Is there a way to quantify how much memory these lists take up? The lists range from lists of integers to lists of variables with dozens of properties. Can I somehow quantify how taxing this is on the app or the end user?
I am trying to write an application that monitors internet usage. So it sort of needs to act like a firewall/proxy, recording each site the computer goes to. It will record all these sites in a log file. Using a proxy server on the network is not an option, each computer running this software needs to be self sufficient. Do you have any suggestions on what to use for this project?
Does a the size of the class affect the memory usage of the application? is it better to break big classes into smaller classes or just group them up into one big class.
I have an ArrayList that stores 100,000+ numbers inside of it. Each number is 10 digits in length or smaller. The program itself has data input into it, of which it loops through the user input to see if any of their numbers are already in the array using if ArrayList.Contains(userinput).
It would appear that when having an ArrayList of this size a LOT of memory is being used. Would there be a faster way to run this, E.g. Database or If TextFile.Contains(Line)?
All I am looking to do is display the current RAM usage being used in a textbox, nothing more nothing less. I will encorperate it into a timer and update automatically, how do I do this ?
How can I get the CPU usage for an individual, specific process? I know how to get the total CPU usage, but not for 1 process. What I ultimately want to do is list all the processes whos cpu usage is greater than zero.
I used 4 seperate pictureboxes to load in each picture. Then I click the option to select X picture, which works. However, if I click another option, the Y picture doesn't load.I tried with:
I have a several C# console applications that basically parse tons of data in memory (LINQ) and output the results to a text file. Now, forget about the writing to the text file for a minute because this is not where the problem is occurring.
When I run the application in debug mode, I will never get it to utilize more than 50% of cpu usage. It will be parsing/massaging hundreds of thousands of records, but only go X fast and utilize 50% of the cpu AT MOST (as viewed in the Task Manager).
I would really like to use 100% of the CPU to make the processing go faster. Does anybody have any insight? I am running Windows XP Professional with Service Pack 3. I have Visual Studio 2008 Professional with Service Pack 1 installed. I have manually set the affinity of the process in Task Manager to a single core on the dual CPU. Sometimes I can catch it utilizing 51% or 52% of the CPU.
I saw some 'offsets' such as: 0x006E71A0and some that were like, Game.dll+8E336CI'd more so think the 0x006E71A0 and the Game.dll+8E336C are among the same format, so i'd like to use that.I have also read somewhere(this could be wrong) that the memory addresses formats are different between VB, C#, and C++.
I've wrote this code to accomplish what the image below looks like. This works fine for anything that is around 40x40 but if I try to do 100x100 it takes forever and sometimes errors out with a window handle error. Once it gets around the 40th column the labels start adding slower and slower. Is there anything I can do to make this more efficient? I added the backgroundworker routine in there to see if it would speed things up at all but it doesn't.
